CHURN-MOTOR.

SPECIFICATION forming part of Letters Patent No. 248,243, dated October11, 1881. Application filed July, 16, 1881. (No model.)

1 To all whom it may concern.-

Be it known that I, M. WEST, a citizenof the United States, residing atHouston, in the county of Chickasaw and State of Mississippi, haveinvented a new and valuable Improvement in Churn-Motors; and I do herebyde clare that the following is a full, clear, and exact description ofthe construction and operation of the same, reference being had to theannexed drawings, making a part of this specification, and to theletters and figures of reference marked thereon.

Figure 1 of the drawings is a representation of a side elevation of myinvention, and Fig. 2 is a view of the opposite side.

This invention has relation to revolx ing churns; and it consists in theconstruction and novel arrangement of the devices for operating thesame, all as hereinafter shown and described.

In the annext d drawings, the letter A designates al'rame, which may beconveniently constructed by securing the uprights B to the sills O, andconnecting said uprights by means of the ties D at their intermediateportions, and the cap-bars E at their upper ends.

' Through bearings a, on the uprights B, extend the journals of theshaft F, which is squared to fit the square bearings b of the churn-caseG, through which it passes, and is provided with a pinion, H.

K representsthe driving-shaft, which isjournaled in bearings c at themiddle portion of the frame below the bearin gs a. On this shaft islocated the large toothed wheel L, which is designed to engage thepinion H of shaft F. This large gear-wheel is loose on the shaft, and isprovided with a pawl, N, which is kept in engagement with theratchet-wheel R by means of a spring, S. The ratchet-wheel R is rigidlyconnected to the shaft K, and by the side of the ratchet-wheel a drum,J, is also firmly secured to said shaft. On the drum Jis wound aroundthe large toothed wheel.

the rope e, which passes thence over a pulley or block, g, which isfastened to the ceiling or other high point, as indicated in thedrawings. To the end of the rope is secured a weight, W, which isdesigned to be sufficient to operate the parts under the force ofgravitation. A crank-handle, V, connected to the end of thedriving-shaft, serves to wind up the rope on the drum.

The churn-ease is designed to be of square or angular formation. and itsopening is provided with threads for the engagement of a screw-top, T,so that there will be no leakage during the revolutions of the churn. t

The operation is as follows: Thechurn having been filled and the ropewound up on the drum, the ratchet will become positively engaged withthe pawl, and will therefore, as the weight descends and the drum turns,carry This whee], although, on account of its large diameter, it movescomparatively slowly, turns the pinion H rapidly, and thereby effectsthe revolution of the churn, which is attached to the pinionshaft.

Having described this invention, what I claim, and desire to secure byLetters Patent, lS

In a churn-motor, the combination, with the churn-shaft F and its pinionH, of the drivingshaft K, the drum J, and ratchet-wheel R, rigidlyattached thereto, the lurge toothed wheel L, loosely engaged with saidshaft, pawl N, pulley'g, rope e, and weight W, substantially asspecified,

In testimony that I claim the above I have hereunto subscribed my namein the presence of two witnesses.

MAROELLUS WEST.
